Rockpro64 pcie kernel delay


Recommended Posts

Hi all,

 

I'd love to run my sas2008 card on armbian.

 

Im currentky testing the ayufan 0.10.12 build and it is working with my sas cards flawlessly even with sas expanders and 16x hdd attached.

On armbian or any other release for that matter there is insufficient boot wait time for to card, i believe these cards take around 400ms to boot with bios rom deleted. The patch provides 1 second wait time.

 

 

Working kernel patch is here thats been pulled into the above release

https://github.com/nuumio/rp64-linux-mainline-kernel/releases

 any chance of having this incorporated?

 

My skillset with kernel/image building is very short in supply so im not sure how much i can do but point me in the right direction and ill try, it appears this is a very usefull feature for those with lsi sas cards for bigger nas boxes.

Armbian is a community driven open source project. Do you like to contribute your code?

My first suggestion is to isolate the patch that makes the changes you need. Right now, your link simply points to a list of zip files with whole kernel sources. Once you have the patch you need, applying it with the Armbian Build System is a piece of cake.

Hmmm mobile will catch you out every time, when i get back to my pc ill have to find the patch again and will update you.

From my reading this is how BSD has also got pcie working on these boards.

 

Of note is this mailing list regarding working thru the exact issue 9 months ago

If you are referring to the info that's necessary for us to help you, as @Werner stated above, you've got it in the forum rules and in the warning you receive when you are going to post. You need to provide that if you want any help from our side.

 

My suggestion assumed that it was you who wanted to try the fix by yourself.
